Be it known that 1, WILLIAM B. Nrcncnson, a citizen of the United States, resldln .xalltjgl apman, in the county of Dickinson an nection with the accompanying drawings,

the invention residing in the construction, combination, and arrangementof parts as claimed.

In the drawings formnig part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1 is a view in elevation of the device forming the subject matter of the invention, showing the arran ement of parts whenthe device is used in t e capacity of a jack. I I

Figure 2 is a plan view of a tire carrying rim showingthe manner of using the device in connection therewith.

Figure 3 is a sectional view taken on line 33 of Figure 2.

Figure 4: is a sectional view 44 of Figure 2. l

Figure 5 is a detail view of one of the swinging arms.

Referring to the taken on line drawings in detail, 10

, indicates generally a screw jack of any wellknown construction, and wherein the operating lever is indicated at 12. Projecting from the housing 13 adjacent the base 14 of the jack are spaced apertured lugs 15 between which is pivoted a hook-like element 16. The purpose of this element will be hereinafter set forth. Secured to the head of the screw is a plate 17, and arranged centrally of the opposed sides thereof are loops .8 received between similar loops 19 formed on the adjacent extremities of swinging members 21.

. Pintles 22 are passed through these loops to swingingly support the members 21.

Bolted or otherwise Suitably secured to each member is an arm 22 which terminates to provide an offset hook-like terminal 23, and these members are used in connection with a tire carrying rim when it is desired to contract or expandthe latter for the purpose above mentioned. When the device is used as a jack, the arms can be swung at any desired angle with respect to the screw, so as to occupy an out of the way position, thereby allowing the head of the screw to be properly positioned beneath that part of the vehicle or object to be lifted.

When the device is used in connection with a tire carrying rim, the latter is laid upon the ground or surface and the device placed within the rim in the manner illustrated in .Figure 2. The base of the jack contacts the and the hook-like terminals of said arms arranged to engage the edge of the rim, appro priate distances from the meeting ends thereof. When associated with the rim in this manner, the bar 25 is properly arranged, depending of course upon whether it is desired to contract or expand the rim. When the screw moves within its housing, a pull is exerted upon the rim adjacent the meeting ends thereof in a manner to separate said ends and allow the rim to contract by reason of its inherent qualities. On the other hand, when the screw is forced outwardly of its housing, the rim is expanded to return the meeting ends to their original position in face to face contact.

'While it is believed that from the fore, going description, the nature and advantages of the invention will be readily apparent, desire to have it understood that I do not limit myself to what" is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim is A combination jack and rim tool comlprising a base, a hollow standard rising t erefrom, a screw operatin in said standard, means for operating said screw, a plate carried by the upper end of the screw, swinging members hingedly connected upon the oppo site sides of said plate, a relatively long arm carried by each membeqand arranged parallel therewith, a hook hike portion pr0 eeting laterally from the outermost end of each farm and adapted to engage said rim spaced parallel lugs projecting from said jack standard at a point adjacent the base, a pivoted hook like member mounted between said lugs and arranged to engage the rim at memos a point immediately beneath said base as and 10 WILLIAM B. NICHOLSON.
